Response to Delegated act on primarily used components under the Net-Zero Industry Act

20 Feb 2025

Why should gas turbines (or dispatchable thermal turbines) running on carbon-neutral fuels be recognised as a final product/specific component considered to be primarily used for the production of net-zero technologies in the Net-Zero Industry Act? Gas turbines and other turbomachinery solutions operating on Carbon-neutral fuels should be considered net-zero technologies because they provide dispatchable, reliable, and low-emission power generation while fully aligning with decarbonisation targets. Below are the key reasons justifying their net-zero status: 1. Zero or near-zero carbon emissions combustion * Hydrogen (H) combustion produces no CO emissions, only water vapour (HO) and small amounts of NO (which can be mitigated with advanced combustion techniques). See (1) ETN Global report on Hydrogen combustion challenges (in the attached document). * Sustainable (bio)fuels (such as biomethane or synthetic fuels) are derived from organic waste, agricultural residues, or captured CO, making their carbon footprint close to neutral when considering the full life cycle. (ref. RED II directive) If a fuel does not contribute additional CO to the atmosphere or is derived from captured carbon, it qualifies as net-zero. 2. Enabling grid stability in energy system with a high level of Variable Renewable Energy sources * Gas turbines operation on hydrogen or biofuel provides fast-ramping, dispatchable power, ensuring grid reliability when solar and wind output fluctuate. See (2) ACER report on Flexibility solutions (in the attached document) * Unlike batteries, gas turbines can store and convert renewable fuels into power with high peak capacity over long durations, complementing seasonal energy storage. Net-zero energy systems require backup solutions for renewablesgas turbines running on hydrogen or sustainable (bio)fuels ensure uninterrupted clean power. See (3) ETN Whitepaper on the Critical role of dispatchable power generation (in the attached document). 3. Scalability and infrastructure readiness * Many existing gas turbine power plants can be retrofitted to run on hydrogen or (bio) fuels, significantly reducing emissions without new infrastructure. See (4) ETN Global report on Hydrogen Gas Turbines (in the attached document) * Hydrogen-ready gas turbines are already being deployed, and (bio) fuels can be used in current systems with minor modifications. A scalable and cost-effective transition to net-zero is possible by leveraging existing assets, rather than building an entirely new power system. 4. Carbon Capture compatibility for additional reductions * Hydrogen and sustainable (bio) fuel-fired gas turbines can be integrated with Carbon Capture, Utilisation, and Storage (CCUS) to further remove any remaining emissions, making them a negative-emissions solution in some cases. Net-zero systems must eliminate residual emissionsCCUS integration ensures turbines go beyond net-zero when needed. Conclusion: Gas Turbines a Net-Zero Technology Gas turbines running on Carbon-neutral fuels fully support a net-zero energy future by: * Producing little to no CO emissions * Providing dispatchable and affordable backup for renewables * Leveraging existing infrastructure for cost-effective decarbonisation * Enabling deeper emissions reductions when combined with CCUS For a secure, flexible, and net-zero energy system, gas turbines running on clean fuels are not just an optionthey are a necessity. Call for action: We advocate that gas turbines running on carbon-neutral fuels should be recognised as a final product/specific component considered to be primarily used for the production of net-zero technologies in the Net-Zero Industry Act.
